I am currently upgrading angular 4 to angular 6 code. I have installed \"rxjs\": \"^6.3.2\" and un-installed rxjs-compact as I have migrated the code to use the new rxjs ope
Both the rxjs and rxjs-compat of the version 6.3.2 worked for me.
npm install rxjs@6.3.2 --save && npm install rxjs-compat@6.3.2 --save
